About this Guide

This guide contains installation, configuration, and operating information for the Extron®

VN-Matrix® VNC 325 encoder/decoders (codecs).

NOTE: This guide describes the operation the VN-Matrix 325 with version 4.6 or later

firmware.

About the VNC 325 Codec

The VN-Matrix VNC 325 video codecs (see figure 1) distribute digital SD, HD-SDI, or 3G-SDI

broadcast quality video and audio content across an IP network using the Extron PURE3

®

Codec algorithm. PURE3 exceeds many of the performance characteristics of existing

compression formats and provides exceptionally robust protection against network errors,

making it ideal for quality-critical applications. The VNC 325 codec can be configured to

operate in one of two modes:

• As an encoder to encode a source and stream it across a network,

• As a decoder to decode a VN-Matrix 325 encoded data stream from a network.

VN-Matrix 325 Serial Digital Over IP CODEC • Introduction 1

Each VNC 325 codec has an integrated web interface. One codec in the VN-Matrix system

must be designated as the system controller, and the controller can be any unit in the

system, whether it is configured as an encoder or decoder. All normal system configuration

and control is via the web interface of the designated controller. Using a computer on the

same network and a standard web browser, such as Mozilla

®

Firefox

®

or Microsoft® Internet

Explorer®, you can configure any VNC 325 unit in the system.

Video signals that are connected to a VNC 325 codec that is configured as an encoder are

compressed into a data stream for transport across a local area or wide area network. At the

far end of the network, one or more VNC 325 codecs configured as decoders decode the

compressed stream back into the original video signal format.

The VNC 325 that is configured as an encoder accepts audio that is embedded in the input

video and that complies with the following SMPTE standards:

• SMPTE 299M — 24-bit digital audio

• SMPTE 272M-A — 20-bit digital audio

The embedded audio groups can be transported with the associated video content. Audio

can be sent as received (transparent mode) or as a single stereo pair (stereo mode). Stereo

mode results in a lower bit rate and reduces the network load. The VN-Matrix system also

supports simple compression of the stereo audio.

A dedicated RS-232 port is available for distributing RS-232 data with the coded/decoded

video, such as for control of projector.

A VN-Matrix 325 system is comprised of at least two devices, one configured as an encoder

and the other as a decoder. However, multiple encoders and decoders can co-exist on the

same network. On a given network, any decoder can display the source provided by any

encoder. Figure 1, on the preceding page, shows a basic VN-Matrix 325 system. In this

example, either of the two encoder streams can be routed to any or all three decoder units.

The configuration of each device, including the source that is displayed at each destination,

can be set using any PC or laptop on the same network, using the VN-Matrix 325 web

pages. In this example, the codec that is labeled IP Decoder 3 is the system controller.

Source (digital video) data from a VNC 325 encoder can be distributed to multiple decoders

and displays (one-to-many) or to a single decoder and display (point-to-point). Video data is

transported from the source (encoder) to the display (decoder) using one of three methods:

• Multicast real time protocol (RTP) — One source (encoder) and an infinite number of

displays (decoders)

• Unicast RTP — Single source (encoder) to single display (decoder), but it can also be

used for up to four displays

• Unicast transport control protocol (TCP) — Single source (encoder) to single display

(decoder). This method should be used only for single point-to-point transfer of data.

Each method, with its advantages and disadvantages and a sample connection diagram, is

described in “Data Transport Methods” in the “Installation“ section.

The units are housed in 1U high metal enclosures that can be mounted in any standard

19-inch rack or under furniture with optional mounting kits.

The external 100 VAC to 240 VAC, 50-60 Hz power supply provides worldwide power

compatibility.

Autodetection — The codecs auto-detect the format of the connected signal. Input sources

are encoded and decoded at their native resolution and format

Audio signal compatability — The codecs support the transport of embedded audio input

data, as described by the SMPTE 299M 24-bit digital audio and SMPTE 272M-A 20-bit digital

audio standards.

Configurable as encoder and decoder —

Encoder signal connections — The unit has three functional BNC connectors for video

connections; an input and two looped outputs.

Decoder signal connections — The unit has two functional BNC connectors for video

and sync connections.

Two levels of operator interface —

Low-level configuration — The Ethernet parameters of each codec in the system are

set using a PC connected to an RS-232 serial port.

Final configuration and operation — After the initial low-level configuration, all

other configuration and operation of the VN-Matrix 325 system is via either of two

Ethernet ports of the system controller unit. A computer that is running on the same

network as either port can control the entire system using the built-in HTML pages of

that unit.

System control — One codec unit in the system is designated as the system controller. The

unit acts as a server for the HTML control interface and holds a record of the configuration

of all VN-Matrix 325 devices on the network. The system controller manages the

communications to all VNC 325 devices. Any codec, whether it is configured as an encoder

or decoder, can be used as the system controller.

Two Ethernet ports — Each unit has two Ethernet ports for network connections:

One RJ-45 port for a Category (CAT) 6 twisted pair (TP) cable

One optical port for a fiber-optic cable

Two RS-232 serial ports —

Remote port — For low-level configuration of the Ethernet parameters of the unit.

RS-232 Over LAN port — For inputting and outputting RS-232 data with the coded

and decoded video, such as for control of projector. This port is also for access to the

built-in alarm relay.

VN-Matrix 325 Serial Digital Over IP CODEC • Introduction 3

Highly efficient compression algorithms — The VN-Matrix 325 system uses a minimal

amount of data to transport video and audio across the network.

NOTE: It is crucial to the effective operation of VN-Matrix 325 that sufficient data

throughput be achieved, especially where multiple sources are encoded.

The network efficiency is directly affected by the speed and configuration of

each element, such as switchers and routers, within its infrastructure. The

VN-Matrix 325 system achieves optimum transmission results over a dedicated

1 Gbps network (1000Base-T, also known as Gigabit Ethernet).

Rack mounting — One or two 1U high, half-rack metal enclosure units can be mounted in

any standard 19-inch rack with optional mounting kits.

Under furniture mounting — Using optional Extron surface mount kit

Power — The external 100 VAC to 240 VAC, 50-60 Hz power supply provides worldwide

power compatibility.

Source (video) data from a VNC 325 encoder can be distributed to multiple decoders and

displays (one-to-many) or to a single decoder and display (point-to-point). Video data is

transported from the source (encoder) to the display (decoder) using one of three methods,

in order of preference, which are detailed in the following sections:

• Multicast real-time protocol (RTP) — Best choice

• Unicast RTP — Second choice

• Unicast Transport Control Protocol (TCP) — Acceptable

You need to select among these three methods using the HTML pages, see “Configure

Encoders or Decoders“ on page 25.

Multicast RTP

The multicast real-time protocol (RTP) data transport method is connected as shown in

figure 3. Multicast RTP is a one-to-many protocol that allows a source to be displayed on

an infinite number of displays. This transport method uses a real-time variation of User

Datagram Protocol (UDP), called RTP. In figure 3, the streaming data is identified as “RTPm”.

NOTES: • The UDP protocol is a standard Internet network protocol that is connection-

less, meaning that it does not use the hand-shaking that provide reliability,

ordering, or data integrity but is overhead intensive. Therefore, UDP can

be unreliable. On the other hand, RTP provides very low latency, which is

important for video transport.

• The VN-Matrix 325 supports IGMP V2 for multicast streaming.

VN-Matrix 325 Serial Digital Over IP CODEC • Installation and Setup 8

This is the recommended transport method for real time video and audio data over an

IP network. However, because RTP is a connection-less protocol, data delivery is not

guaranteed. Where data packets are lost (such as due to excessive network traffic), the

PURE3 algorithm carefully manages the data stream to minimize any image disruption.

NOTE: In figure 3, IP decoder 3 is designated as the system controller.

Unicast RTP

Like multicast RTP, the unicast RTP data transport method uses a real-time variation of the

UDP protocol that is connected as shown in figure 4. Unicast RTP differs from multicast RTP

in that it is a point-to-point protocol that uses a separate data stream for each decoded

display. The VN-Matrix 325 system can support up to four displays (decoders) from one

source (encoder), but such a configuration uses four separate data streams and results in

four times the network bit rate as a single display (decoder) configuration.

This method can be used in place of multicast RTP, when the network infrastructure does

not support or the local IT administration will not allow multicast traffic. Contact the system

administrator.

In figure 4, the four streams of data are identified as “RTP

1

” through “RTP

4

”.

Figure 4. Typical Unicast RTP Application

As with multicast RTP, it is a connection-less protocol and data delivery is not guaranteed

Where data packets are lost (such as due to excessive network traffic), the PURE3 algorithm

carefully manages the data stream to minimize any image disruption.

NOTES: • In figure 4, the IP encoder is designated as the system controller.

• In unicast RTP mode, while the system supports up to 4 simultaneous

streams, the rate is dependant on the total aggregated bit rate, which must

not exceed 270 Mbs.

VN-Matrix 325 Serial Digital Over IP CODEC • Installation and Setup 9

Unicast TCP

The unicast TCP data transport method uses standard TCP protocol and should be used for

single point-to-point transfer of data only. This method is connected as shown in figure 5.

NOTES: • Multiple decoder connections are theoretically possible using this method

but not recommended. Each additional connection creates extra loading on

the encoder CPU, which ultimately results in poor display performance. In

addition, multiple TCP streams carrying the same source data is an inefficient

use of network bandwidth.

• While figure 5 shows two decoders, in the scenario shown only IP decoder 1

is set to actively decode data that is streamed to it. IP decoder 2 may be

in standby (set as Device Type: None, see “Configure Encoders or

Decoders“) or may be receiving streamed data from another encoder.

• In figure 5, IP decoder 2 is designated as the system controller.

Figure 5. Typical Unicast TCP Application

TCP is a connection-based protocol. Data is guaranteed to be delivered, however excessive

network traffic, which impacts real-time performance, may delay delivery.

Data and Control Routing

The system can be used over both switched (single segment) and routed (multi-segment)

networks

The VN-Matrix 325 system can be configured to run using either a single LAN port (1 or 2)

or both LAN ports. In the single port configuration, all data (image, audio, control, and

monitoring) is transported on the designated port. In the dual port configuration, image and

audio data is transported on one connection while the other LAN port is used for monitoring

and or management functions.

All system control is managed by the VNC 325 that has been designated as the controller.

Any changes made in the network browser are sent to the affected codec from the

controller via the network that has been assigned for streaming. The browser is accessible

via either network port on the unit that is configured as the controller.

Video and audio data can be transported over either of the LAN ports on the VNC 325 and

are independent of the system control data.

Example 1: Switched and isolated network configuration

NOTE: It is immaterial, in this example, which codec is the encoder and which is the

decoder. These functions are not identified in figure 6.

Figure 6 shows two VNC 325 codecs that are configured to work across two switched and

isolated networks. Codec 1 is configured as the controller, via LAN port 1. The controller

handles all normal system configuration and control via its web interface.

This example consists of two networks, connected to the VN-Matrix system as follows:

• Network 1, connected to LAN port 1 (RJ-45 port), the “green” network — The

encoder streams video on this network and it is also used for system control and

monitoring.

NOTE: Selection of this network for streaming is via the built-in HTML network

interface. This selection is defined in the management interface, described

later (see “Configure Encoders or Decoders“).

• Network 2, connected to LAN port 2 (the fiber optic port), the “red” network —

This network is separated from the streaming network. This network also can be used

for system control and monitoring if preferred.

NOTE: The controller codec responds to inquiries on LAN port 2 as well as LAN

port 1.

• A network management server can also be integrated if required.
